Application November 27, 1937, Serial No. 176,868

2 Claims.

This inventionv relates broadly to devices for applying a coating to strips, particularly strips of fabric; and the present invention is particularly designed for applying plaster of Paris, in

5 powdered form, to strips of bandage, and more particularly to gauze, in roll form, and as generally used for bandages.

An object of the invention is to provide a device whereby plaster of Paris may be applied to rolled bandages in a quick, positive and eflicient manner.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a longitudinal sectional view through the device,

Figure 2 is a top plan view thereof, and

Figures 3 and 4 are vertical transverse sectional views taken substantially on the lines 33 and 4-4 of Figure 1.

Referring to the drawing by reference numerals it will be seen that the device, in the preferred embodiment thereof, is preferably formed of metal and comprises a substantially-rectangular relatively shallow pan or receptacle 5 having a bottom wall 6, side walls I, and end walls 8 and 9.

At one end thereof the bottom wall 5 is ex- 0 tended beyond the wall 8 of the pan as at III to provide a platform from which the coated bandage feeds to be rolled on a shaft H;

Shaft H is rotatably supported between a pair of posts 12 that rise from a foot piece l3 inte- 5 gral with the bottom extension III of the pan through the medium of a perpendicular flange or web I4.

The foot l3 and flange ll provide a support for the forward end of the device while the rear 0 end of the device is supported by a substantially U-shaped stand IS the sides of which at their upper ends are suitably secured to or otherwise made integral with the bottom 6 of the pan at the end 9 of the pan.

To accommodate the bandage strip [6 walls 8 and 9 at the lower edges thereof are provided with slots I1 and II respectively.

The sides 1 of the pan at the end 9 thereof are extended beyond said end of the pan as at 50 I9 and said side extensions I9 are suitably apertured to accommodate a. rod or shaft 20 on which the bandage roll it is supported so that with the strip of bandage trained over the bottom 6 of the 55 pan and through the slots l8 and II the bandage will feed from the roll it onto the shaft ll, passing through the pan 5.

The pan 5 is adapted to contain to a suitable level the powdered material 2|, in the present instance plaster of Paris.

For the most part thereof the powdered material 2l is conflned in the pan between the wall 9 thereof and a transversely disposed brush 22.

Brush 22 is of the bristle type and embodies a head 23 which at its opposite ends is provided with outstanding lateral flanges 24. The flanges 24 are provided with vertical rows of apertures 25 for selective alignment with apertures in the sides I of the pan whereby to accommodate pins 26 through the medium of which the brush 22 is secured at the desired vertical position of adjustment with the bristles in wiping contact with the bandage strip l6 as the latter feeds through the pan 5.

The brush 22 will serve to work the powdered plaster of Paris material into the gauze or fabric l6.

For catching any loose powder falling from the gauze It as it winds into a roll on the shaft ll there is provided a pan 28 which is of such dimension as to accommodate therein the foot l3 as clearly shown in the drawing.

It will thus be seen that with a device of this character plaster of Paris, in powdered form, may be readily and quickly applied to rolled bandages.

It is thought that a clear understanding of the construction, utility and advantages of an invention of this character will be had without a more detailed description.

Having thus described the invention what is claimed as new is:-

1. A device for applying plaster to a roll bandage comprising a pan including a bottom wall, a pair of side walls and a pair of end walls, said end walls having slots in their lower ends, and said side walls at one end of the pan projecting beyond the adjacent end wall, a transverse member supported by said side wall extensions for supporting a bandage roll, a brush supported in the pan adjacent the other end wall, the plaster being placed in the pan between the brush and the first-mentioned end wall and on that portion of the strip of bandage which passes between the first-mentioned end wall and the brush, said bottom wall having a platform forming extensions at its rear end for forming a rest for a portion of the strip after the same is passed through the pan, a depending flange at the rear end of the bottom wall of the platform, a horizontal foot portion connected with the lower edge of the flange, uprights on said foot portion, a shaft journaled in the uprights for receiving an end of the treated strip, a small receptacle in which the foot portion rests and a leg member depending from the front end of the pan.

2. A device for applying plaster to a roll bandage comprising a pan including a bottom wall, a pair oi side walls and a pair of end walls, said endwalls having slots in their lower ends, and said side walls at one end of the pan projecting beyond the adjacent end wall, a transverse member supported by said side wall extensions for supporting a bandage roll, a brush supported in the pan adjacent the other end wall, the plaster being placed in the pan between the brush and the first-mentioned end wall and on that portion of the strip of bandage which passes between the first-mentioned end wall and the brush, said bottom wall having a platform forming extension at its rear end for forming a rest for a portion of the strip after the same is passed through the pan, a depending flange at the rear end of the bottom wall of the platform, a horizontal foot portion connected with the lower edge of the flange, uprights on said foot portion, a shaft journaled in the uprights for receiving an end of the treated strip, a small receptacle in which the foot portion rests and a leg member depending from the front end of the pan, and means for adjusting the brush vertically in the pan.
